Hi,
Uncheck the option in PE to run at startup & reboot.
Run it as Admin, whenever you need to see something, I even manually created a Start Menu entry shortcut to run it easier.
After reboot, it should no longer be listed in Services, neither in msconfig.
I only see it in taskmgr when I manually run it and it vanishes when I close PE.
That way, I have no related entries in Norton Security History logs at the exception that it has been detected at launch and also it was never blocked from running without any intervention from my part.
Leave Tamper Protection always enabled.
Hope this will resolve your issue.,
Regards,
